x² - 8x = -7.
[tex]------------------[/tex]
[tex]\sf{{ x² - 8x = -7 }}[/tex]
[tex]\sf{{ {x}^{2} - 8x + 7 = 0 }}[/tex]
[tex]\sf{{ {x}^{2} - 7x - x + 7 = 0 }}[/tex]
[tex]\sf{{ x(x - 7) - (x - 7) = 0 }}[/tex]
[tex]\sf{{ (x - 7)(x - 1) = 0 }}[/tex]
[tex]\sf{{ x - 7 = 0 \: or \: x - 1 = 0 }}[/tex]
[tex]\large \rm Final \: Answer:[/tex]
